Oh wow, I am glad that Samson & everyone else is alright. Like you said it's just one fo those things that happen.

You guys sure got lucky. The best & safest way to seperate dog fights (2 people work best) is to pull each dog away from each other by their hind legs (wheelbarrow style) or by their tails if you can't get to their hind legs.

Oh yeah & NO dog has an actual "lock jaw". It is impossible.

I hope Samson heals fast & is back out there playing in no time.
